Tivoli Storage Manager for Windows Administrator's Guide
Tivoli Storage Manager (TSM) is an enterprise-wide storage management
application for the network. It provides automated storage management
services to multivendor workstations, personal computers, and local area
network (LAN) file servers. TSM includes the following
components:
- Server
- Allows a server system to provide backup, archive, and space management
services to workstations. The server maintains a database and recovery
log for TSM resources, users, and user data.
The server controls storage objects called storage pools. These are
groups of random and sequential access media that store backed-up, archived,
and space-managed files.
You can set up multiple servers in your enterprise network to balance
storage, processor, and network resources. TSM allows you to manage and
control multiple servers from a single interface that runs in a Web browser
(the enterprise console).
The TSM server comes with an interface to server utilities for tasks such
as configuring devices.
- Administrative interface
- Allows administrators to control and monitor server activities, define
management policies for client files, and set up schedules to provide services
at regular intervals. Administrative functions are available from an
administrative client command line and from a Web browser interface.
A server console is also available.
- Backup-archive client
-
Allows users to maintain backup versions of their files, which they can
restore if the original files are lost or damaged. Users can also
archive files for long-term storage and retrieve the archived files when
necessary. Users themselves or administrators can register workstations
and file servers as client nodes with a TSM server.
- Application program interface (API)
-
Allows users to enhance existing applications with back up, archive, restore,
and retrieve services. When users install the TSM API client on their
workstations, they can register as client nodes with a TSM server.
TSM also supports the following client programs:
- Tivoli Data Protection for applications (application clients)
-
Allows users to perform online backups of data that is used by applications
such as database programs. After the database initiates a backup or
restore, the application client acts as the interface to TSM. The TSM
server then applies its storage management functions to the data. The
application client can perform its functions while users are working, with
minimal disruption.
- Tivoli Space Manager
-
Provides space management services for workstations on some platforms.
Tivoli Space Manager users can free workstation storage by migrating less
frequently used files to server storage. These migrated files are also
called space-managed files. Users can recall space-managed
files automatically simply by accessing them as they would normally.
Tivoli Space Manager is also known as the hierarchical storage management
(HSM) client.
Figure 1 shows an example of a client/server environment with
TSM.
In this example, an administrator uses an administrative interface to monitor
the system, for example, the administrative client program that is installed
on a workstation. An administrator can also monitor a server by using a
Web browser with the appropriate Java support.
The backup-archive client program and HSM client program have been
installed on workstations connected through a LAN and registered as client
nodes. From these client nodes, users can back up, archive, or migrate
files to the server.
Using rules in TSM policies that are assigned to files, the server stores
client files on disk, optical, or tape volumes in server storage.
Server storage is divided into storage pools that are groups of storage
volumes.

The following sections present key concepts and information about
TSM. The sections describe how TSM manages client files based on
information provided in administrator-defined policies, and manages devices
and media based on information provided in administrator-defined TSM storage
objects.
